I use the same AV8R, with CH pedals, it's a good all around aviation joysick. the problem about being to sensitive is more a problem with FS than it is the stick, especially with small singles....the sim seems less touchy and a bit easier to handle in bigger planes.
If I could make a few suggestions about the AV8R.......I have one throttle set to adjust the throttle and the other is set to adjust the prop(going back to the original concept of this thread

) if your flying the mooney all the time, you really should give that a try. also if your using the VC all the time(as I do) I like to have the button below the hat as center veiw, that way you can always reset your veiw easily if your looking around and then you need to get back to forward veiw quickly, then its right there under your thumb 8-) also I like to have trim set-up on one of the toggles, and flaps up and down on another.........just a few ideas for you that I've found to work well for me.
